Description

Technical Field

[0001] The utility model relates to the technical field of mixing blades, in particular to a mixing blade structure of a portable mixer. Background Art

[0002] Due to the common needs of daily life for pulverizing food, blending juice, and other tasks, portable blenders have gradually become popular and have become a common small appliance in every household kitchen. The blending blade is a key component of a blender. Existing blender blades generally consist of at least two blades with inclined surfaces: one facing upward and the other facing downward, ensuring complete pulverization without missing any ingredients.

[0003] Utility model CN216317225U proposes a mixing knife and food mixer. The mixing knife comprises an upper blade, several spoilers, and a lower blade. When activated, the material is mixed and cut by the upper and lower blades, respectively, while the spoilers create a diversion effect, improving mixing efficiency. However, this type of knife has a complex structure, high production costs, and is difficult to clean and maintain, easily damaged, and thus affects the user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a mixing blade structure of a portable mixer, which has a simple structure, low production cost, is easy to clean and maintain, and solves the problems of the prior art.

[0005] The present invention provides a mixing blade structure for a portable blender through the following technical scheme, comprising a wing root and a first blade wing and a second blade wing extending outward from the periphery of the wing root at positions opposite to each other, a mounting hole being provided at the center of the wing root, and a blade being provided on the blade, characterized in that the first blade wing is a two-section structure bent in an L-shape downward relative to the wing root plane, and the second blade wing is a three-section structure bent in a U-shape downward relative to the wing root plane.

[0006] Furthermore, the angle α at which one section of the first blade is bent downward relative to the blade root plane is 45-80°, and the angle β at which the second section of the first blade is bent upward relative to the first section of the first blade is 20-40°.

[0017] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0018] The components of the embodiments of the present application generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the present application.

[0019] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0020] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0022] The present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 3As shown, the utility model provides a mixing blade structure for a portable blender, which includes a wing root 1 and a first blade wing 3 and a second blade wing 4 extending outward from the periphery of the wing root 1. A mounting hole 2 is provided at the center of the wing root, through which the blade can be mounted on the blade holder shaft of the blender, and the rotation of the shaft drives the blade to rotate. The two blades have different shapes and bends. The first blade wing 3 is a two-section structure that is bent downward in an L shape relative to the plane of the wing root 1. Specifically, the angle α of the first section 3a of the first blade wing relative to the plane of the wing root 1 is 45-80°, and the angle β of the second section 3b of the first blade wing relative to the first section 3a of the first blade wing is 20-40°. It can be seen that the main function of the first blade wing 3 is to stir and crush the material that sinks to the bottom of the mixing cup body. The second blade 4 has a three-segment structure that bends downward in a U-shape relative to the plane of the blade root 1. Specifically, the angle γ of the downward bend of the first segment 4a of the second blade relative to the plane of the blade root 1 is 45-80°. The angle θ of the upward bend of the second segment 4b of the second blade relative to the first segment 4a is 45-80°, with θ being equal to γ. The angle ζ of the upward bend of the third segment 4c of the second blade relative to the second segment 4b is 60-85°. Because the third segment 4c of the second blade is an upwardly inclined surface, the second blade 4, in addition to stirring and crushing the material, can also form a vortex during rotation, pushing the material at the bottom upward, thereby achieving more even material distribution and more thorough stirring.

[0024] Preferably, in this embodiment, the angle α at which one section 3a of the first blade is bent downward relative to the plane of the wing root 1 is 65°, the angle β at which the second section 3b of the first blade is bent upward relative to the first section 3a of the first blade is 30°, the angle Y at which one section 4a of the second blade is bent downward relative to the plane of the wing root 1 is 65°, the angle θ at which the second section 4b of the second blade is bent upward relative to the first section 4a of the second blade is 65°, and the angle ζ at which the third section 4c of the second blade is bent upward relative to the second section 4b of the second wing is 80°.

[0025] Furthermore, the first blade edge 5 on the first blade wing 3 and the second blade edge 6 on the second blade wing 4 are staggered and positioned on opposite sides of each other. When the blades rotate clockwise, the blades face the material to cut. Furthermore, the blades and blade root 1 are integrally formed, making the blade structure more robust and less susceptible to damage. Unlike existing blenders, which often use two or more separate blades, this new blender is simpler and more robust.

[0026] In this technical solution, the mixing blade of the portable blender adopts an integrally formed single-piece blade structure, and the blade wings on both sides are respectively arranged to bend L-shaped and U-shaped, which takes into account the advantages of simple structure while ensuring the mixing efficiency, thereby achieving the effect of convenient cleaning and maintenance, extending the service life, and improving the user experience.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
